A Tcl Routing Script Example

The following is an example of a simple Tcl routing script for Virtuoso Space-based Router. The script assumes that you have already opened your design.

set_treat_via_as_abstract -abstract true
set metal_layers [get_layers -material metal]
set_treat_blockage_as_metal -layers $metal_layers -min_width false -min_space true -override true -force_min_space false
global_route
local_route
croute
detail_route

Output Example

The following is an example of Transcript area output when the routing script is invoked.

set_treat_via_as_abstract -abstract true 
0
set metal_layers [get_layers -material metal] 
"metal1" "metal2" "metal3"
set_treat_blockage_as_metal -layers $metal_layers -min_width false -min_space true -override true -force_min_space false
0

During global route, congestion analysis is run at the start and end of each pass. The initial congestion analysis divides the design into square gcells, determines the resources available for each gcell, and outputs a congestion (Gcell) summary.

The congestion summary indicates the following:

The number of gcells for each metal layer by type: cell, edge, and down-via
The number and percentage of overcongested gcells for each grouping
The gcell resource usage (The <10% column is the number of gcells using less than 10% of their resources, the 10% column is the number of gcells using at least 10% but less than 20% of their resources, and so on)
The number of gcells with 100% blockage (Blk%)

The croute command lays down as many wires as possible along routing conduits. Its goal is to keep the remaining missing connections short in length and to ensure that spacing violations that are created in this step can be corrected in the detail route step.

Here, global routes have been replaced by detail routes and guides.

In the final step of the routing flow, Space-based Router and Chip Optimizer attempts to complete all connections according to the design rules. In this example, one cycle is run with multiple passes.
